I'm trying to use Advanced Find and Replace in Batch Replace mode to replace unicode characters with non-unicode characters, I tried what the help documentation shows \x{0543} but I get a popup dialog error
"search For" partHex Code After \x is Too Big (pos 6)

\x{nnnn} seems to work in the search field in Batch Replace mode on hex number as large as \x{00FF}.

The file I dowloaded had 487,936 bytes, larger than my original AFR.exe
487,424;
When I start the new executable it still reports the same version 2.2 as my current version, but that may not mean anything much.

Thanks again for the response. I tried it again. I think I'm running into a different problem now. The file I tried to run AFR against was UTF-8 format, I think UTF-8 files have some characters that are 1 byte, and some characters that are 2 bytes (like my character \x{0578}). The resulting file I had didn't seem to get substitutions but rather the 2 byte unicode characters were split to 2 1 byte characters (doubling number of characters in the text file, where the words don't quite make sense). I think I'll wait for future release of AFR if it will support reading UTF-8 files.
